soc/intel/cannonlake: Hook up IGD config to option API

Browse source 
Hook up the IGD config options IgdDvmt50PreAlloc and ApertureSize to the
option API, so they can be configured at runtime without recompilation.

The Aperture size falls back to the FSP default value, so no change if
unconfigured.
